Ergonomics - HP DV6 or Compaq CQ61

I am trying to decide between these two laptops...

HP Pavilion DV6 Entertainment Laptop, Turion II M500 2.2GHz, 3GB RAM, 320GB HDD, 15.6" WXGA, DVD±RW, Radeon HD3200, Windows 7 Home

Compaq Presario CQ61 Laptop, Turion II M500 2.2GHz, 3GB RAM, 320GB HDD, 15.6" WXGA, DVD±RW, Webcam, Windows 7 Home

I'm tempted by the spec of the DV6, but I wonder about the ergonomics. If you use either of these laptops, could you please comment on these points:
- keyboard comfort and whether there is much rattle/noise
- any keys that stick or don't respond smoothly
- whether the trackpad is smooth and responsive
- if the wrist rest area gets hot/sticky

Thank you.
